Overview1

BenefitsHigh efficiencyfor a fast return on investment

When developing SIMOGEAR geared motors, significant em-phasis was placed on achieving the highest possible energy efficiency.

Using the plug-on pinion principle in the first SIMOGEAR gear-box stage, higher transmission ratios are achieved when com-pared to gearboxes with slip-on pinion.

This means that frequently instead of 3-stage gearboxes with an efficiency of approx. 94 %, 2-stage helical and parallel shaft gearboxes with a high efficiency of 96 % can be used.

2-stage SIMOGEAR bevel geared motors B have a mechanical efficiency of 96 %. With a range of transmission ratios from i = 3.5 to 60, they have been specifically designed to address the requirements in conveyor technology.

Together with the new Siemens 1LE1 motors for efficiency classes IE2 (High Efficiency) and IE3 (Premium Efficiency), SIMOGEAR geared motors allow a high amount of energy to be saved and reduce the stress on our environment.

Extremely compact and low weightfor easy handling in the machine or system in the smallest space

An integrated end shield instead of an adapter plate and end shield reduces the weight and space required in your machine or system. In addition, interfaces and sealing joints are reduced as a result of the integrated end shield.

With the SIMOGEAR bevel gearboxes, the length was able to be significantly reduced through an optimized bearing design.

SIMOGEAR helical gearboxes D/Z29 to D/Z39 (200 Nm), parallel shaft gearboxes F29 (150 Nm), bevel gearboxes B19 to B49 (450 Nm) and helical worm gearboxes C29 (100 Nm) have an aluminum gearbox housing.

Harmoniously coordinated modular systemto provide the optimum solution for your particular drive task

The fine size graduations of SIMOGEAR gearboxes provide you the optimum drive for every application regarding gearbox type, rated output torque and transmission ratio.

When developing SIMOGEAR geared motors, significant em-phasis was placed on achieving well-balanced gearbox properties.

With SIMOGEAR geared motors you can depend on harmonized and coordinated properties regarding:7 Maximum output torque7 Permissible radial force7 Output shaft diameter7 Bearing service life7 Housing stiffness7 Gearing reliability (fatigue endurable)7 Shaft strength (fatigue endurable)

Fine ratio stagesto always obtain the output speed required

With their wide range of transmission ratios, from very low up to very high, SIMOGEAR geared motors provide the necessary flexibility for your drive application.

As a result of the wide ratio range, 4-pole induction motors can be mainly used the most cost-effective solution.

Further, the gearboxes are quieter as a result of the lower circumferential velocity of the first gearbox stage.

Intelligent sealing conceptfor a high degree of maintenance friendliness

An optimally coordinated sealing concept is available for the SIMOGEAR gearbox output shaft to address the various appli-cation areas and ambient conditions.

Gearbox sizes 19 and 29 are lubricated for life.

All SIMOGEAR geared motors with venting have as standard a pressure breather valve.

The MODULOG modular principlefor the highest degree of flexibility

The motors used for the SIMOGEAR geared motors have a mod-ular design using our well-proven MODULOG modular principle.

The core of the modular system is a basic motor dimensioned for international line supply conditions with power ratings extending from 0.09 up to 55 kW (4/2/6/8-pole).

At the non-drive end, you have an individually configurable mounting shaft system, e.g. for brakes, backstop, rotary pulse encoder, external fan and canopy.

This guarantees high availability as well as short delivery times.

Notes on selection tables1

Structure of the tables for geared motors up to 55 kWIn the selection tables you will find the most frequently used ver-sions and combinations of geared motors sorted according to the motor power. Additional combinations can be selected with our SIMOGEAR Configurator.

The power ratings and torques specified in the catalog refer to mounting position M1 and comparable types of construction, where the input stage does not run completely immersed in oil. Further, standard equipment and standard lubrication of the geared motors as well as normal ambient conditions are assumed.

The specified output speeds are guide values. You can calculate the rated drive speed based on the rated motor speed and the transmission ratio. Please note that the actual output speed will depend on the motor load and the line supply conditions.

CEL China Energy Label

China introduced mandatory energy efficiency labeling for elec-tric motors in June 2008.

From September 1, 2008, and until the transition phase expires, the affected electric motors may only be imported into China and sold in the country with a valid "China Energy Label".

The motor must be labeled with the "China Energy Label" sticker, which states the efficiency class.

In addition to the Energy Label (dimensions, 80 x 54 mm) the efficiency is also stamped on the rating plate.

2-pole, 4-pole and 6-pole motors with a line frequency of 50 Hz and a rated voltage of up to 1000 V must be appropriately marked. Efficiency classes 2 and 3 apply here to motors with rated powers from 0.75 to 375 kW.

Motors for the Eurasian market SIMOGEAR geared motors are certified for the Eurasian economic area.

In the Russia, Kasachstan and Belarus customs union, new technical regulations and uniform conformity requirements (EAC) have been introduced. These replace the previous GOST-R certificates which thus lose their validity.

The certificate is mandatory for export and is required by the customs authorities.

The EAC certificate is valid for all geared motors. For gearboxes with adapters the EAC certificate is not necessary because the EAC certificate only refers to the motor.

Explosion protection according to ATEXSIMOGEAR gearboxes are available for operation in hazardous areas. The explosion-proof versions of the helical, parallel shaft, bevel, helical worm and worm gearboxes comply with Directive 94/9/EC (ATEX) which came into force on January 1, 2003.

The gearboxes are approved for use in zones 1 and 2 (gases) and zones 21 and 22 (dust).

Use in explosive atmosphere G (gases) is permissible for tem-perature classes T1 to T4. With use in explosive atmosphere D (dust), it must be noted that the maximum permissible tempera-ture for the gearbox is 120 C.

Energy efficiency1

Efficiency classes acc. to IEC 60034-30:2008Various energy efficiency standards exist worldwide for induc-tion motors. To promote international harmonization, the interna-tional standard IEC 60034-30:2008 (Rotating electrical machines Part 30: Efficiency classes of single-speed, three-phase, cage-induction motors (IE code)) was drawn up. This classifies low-voltage induction motors according to new efficiency classes (valid since October 2008). The efficiencies of IEC 60034-30:2008 are based on losses determined in accor-dance with the IEC 60034-2-1:2007 standard. This has been valid since November 2007 and will replace the standard IEC 60034-2:1996 effective November 2010. The supplemen-tary losses are now measured and no longer added as a per-centage.

IE efficiency classes IE1 = Standard Efficiency IE2 = High Efficiency IE3 = Premium Efficiency IE4 = Super Premium Efficiency

Fig.1/17 IE efficiency classes in accordance with the power rating

Measuring method according to IEC 60034-2-1:2007 for determining the efficiency

With the measuring method, the supplementary losses are no longer applied as a percentage (0.5 %), but instead they are de-termined with measurements according to IEC 60034-2-1: 2007. The nominal efficiencies are therefore reduced from EFF1 to IE2 and from EFF2 to IE1, even though there have been no technical or physical changes to the motors.

Previously: PLL = 0.5 % of P was added

Now: PLL = individual measurement

PLL = load-dependent supplementary losses

Fig.1/18 IE1-IE3 efficiencies 4-pole at 50 Hz

The following table shows examples of the efficiency values according to the new and old methods for calculating losses.

Background information

Comprehensive laws have been introduced in the European Union with the objective of reducing energy consumption and therefore CO2 emissions.

EU Directive 640/2009 concerns the energy consumption or efficiency of induction motors in the industrial environment. This has been amended in part by Directive 4/2014. These directives are now in force in every country of the European economic area.

The Energy Policy Act (EPAct) was superseded in December 2010 by the Energy Independence Security Act (EISA).

Since December 2010, EISA has extended the minimum legal efficiency class requirements and the following motors must fulfill the NEMA Premium Efficient Level: 1 to 200 hp 2, 4 and 6-pole 230 V, 460 V

In addition, the following motors, for example, must fulfill the NEMA Energy Efficient Level: 201 to 500 hp 2, 4, 6 and 8-pole All voltages < 600 V except 230 V and 460 V Footless motors (IM B5 and other flange types) NEMA design C (increased starting torque) Geared motors

Geared motor noiseSIMOGEAR geared motors have noise levels below the permis-sible noise levels defined for gearboxes in VDI Guideline 2159 and for motors in IEC 60034-9.

When used in conjunction with the gearboxes, the motor noise values LpfA or LWA increase on average by 3 to 5 dB (A).

The circumferential velocity of the motor pinion has a significant influence on the additional gearbox noise level. This is the rea-son that higher speeds or low transmission ratios result in higher noise.

Here, SIMOGEAR geared motors provide a decisive advantage, as the motor plug-on pinion allows transmission ratios of up to 12 in the input stage.

Motor noise in line operationThe noise level is measured according to ISO 1680 in a low-re-flection room and is specified as A-weighted measuring surface sound pressure level LpfA in dB (A). This value is the spatial average value of the sound pressure levels measured at the measuring surface. The measuring surface is a cube 1 m away from the surface of the motor. The sound power level is also specified as LWA in dB (A).

The values specified in the motor selection tables apply to the motor without gearbox at 50 Hz Selection and ordering data page 8/14.

The tolerance is +3 dB. At 60 Hz, the values are approximately 4 dB (A) higher. Noise values for inverter operation on request.

Standards

Designs to AGMA available on request.

Gearbox efficiencyThe efficiency of the gearbox is determined in part by the gear teeth, the rolling-contact bearing friction, and the shaft seal friction.

Helical, parallel shaft and bevel gearboxes

SIMOGEAR helical, parallel shaft, and bevel geared motors have a very high efficiency. Generally, efficiencies of 96 % (2-stage) and 94 % (3-stage) can be assumed. These gearbox types can be operated with energy-efficient motors to create an excellent solution.

Helical worm and worm gearboxes

The first stage of the helical worm gearbox is designed as a helical stage. With the optimally tuned transmission ratios of the worm stage, the best possible overall efficiency is achieved, which is considerably higher than that of worm gearboxes alone.

SIMOGEAR helical worm gearboxes exhibit efficiency levels of between 65 and 90 %. Precise efficiency data can be found in the tables in chapter "Helical worm gearboxes".

The high degrees of efficiency ensure that the SIMOGEAR helical worm gearboxes are not self-locking.

Running-in period

The tooth flanks on new helical worm and worm gearboxes will not yet be fully smoothed, meaning that the friction angle will be greater and efficiency lower during the running-in period. The higher the transmission ratio, the more pronounced the effect.

The running-in process should take approximately 24 hours of operation at full load. In most cases, the catalog values will then be reached.

Self-locking with worm gearboxes

In respect of restoring torques on worm gearboxes, the effi-ciency is considerably reduced in comparison to standard effi-ciency. The restoring efficiency can be calculated as follows: ' = 2 - 1/. At a standard efficiency of 0.5, worm gearboxes are usually self-locking, which is determined by the particular lead angle of the worm gear teeth.Self-locking only occurs with certain combinations of SIMOGEAR gearboxes and is not always of benefit, as the associated loss of efficiency is then relatively high, which in turn requires increased motor power.

A worm gearbox is "self-locking while stationary" (static self-locking), if it is not possible to start from stationary when the worm wheel is driving. A worm gearbox is "self-braking while running" (dynamic self-locking), if it is not possible to continue running when the worm wheel is driving while the gearbox is running - that is, if the running gearbox comes to a stop while the worm wheel is driving.

Shocks can neutralize self-locking. A self-locking gearbox is, therefore, no substitute for a brake or backstop. If you want to use the self-locking braking effect for a technical purpose, please contact us.

Efficiency optimization

As result of the large range of transmission ratios, in many cases, instead of a 3-stage gearbox, a 2-stage SIMOGEAR gearbox can be used.

This means that the efficiency is improved by approximately 2 % when compared to conventional drives.

Further, the efficiency can be improved by optimizing the mount-ing position and the input speed.

Splashing losses

For certain gearbox types of construction, the first stage can be completely immersed in the gearbox oil. In the case of large gearboxes with a high input speed, particularly with vertical mounting positions, this may lead to increased splashing losses, which cannot be neglected.

If you wish to use gearboxes such as these, then please contact Siemens. If at all possible, you should choose horizontal types of construction in order to keep splashing losses to a minimum.

Service factorDetermining the required service factor

The operating conditions are crucial in determining the service factor and for selecting the geared motor. These are taken into account with service factor fBtot.

In standard operation, i.e. with a uniform load of the driven ma-chine, small masses to be accelerated, and a low number of starting operations, a service factor of fBtot = 1 can be selected.For different operating conditions, the service sector can be taken from the tables. When the motor power and the gearbox output speed are known, a gearbox type is selected with a service factor that meets the following condition:

fBtot = fB1 fB

The gearbox size or rated gearbox torque and the resulting ser-vice factor are not standardized and depend on the manufac-turer.

Determining the load classificationThe service factor of the driven machine fBtot is determined from the load classification, number of starting operations, and oper-ating period per day.

The operating conditions can vary greatly. To determine the ser-vice factor, empirical values can be derived from the configura-tion of other similar applications. The driven machines can be assigned to three load groups according to their load classifica-tion. These groups are evaluated according to the mass accel-eration factor mAF.Load groups of driven machines

Note:

When selecting and dimensioning drives with the following special application conditions, please contact Siemens. Frequent reversing Short time and intermittent operation Abnormal temperatures Reversal braking Extreme and/or circulating radial forces at the gearbox output

shaft Fluctuating loads

Mass acceleration factor

The mass acceleration factor mAF is calculated as follows:

All external moments of inertia are moments of inertia of the driven machine and the gearbox, which are to be reduced to the motor speed.

The calculation is made using the following formula:

In most cases the relatively insignificant moment of inertia of the gearbox can be ignored. The mass acceleration factor mAF is calculated as follows with reference to the gearbox and the adapter:

Service factor (continued)Service factors for helical worm gearboxes and worm gearboxes

With helical worm gearboxes and worm gearboxes, two addi-tional service factors are used which take the duty cycle and am-bient temperature into account. These additional factors can be determined from the graphs opposite. The total service factor is thus calculated as follows:

Fig. 2/2 Service factor "ambient temperature"

Example calculation for helical worm gearbox

Mass acceleration factor 2.5 (load classification II), runtime 15 hours per day (read at 16 hours) and 70 starts per hour result in a service factor of fB1 = 1.4 according to the servicefactor table.

A load duration of 30 minutes per hour gives a duty cycle (DC) of 50 %. Thus, the service factor is fB2 = 0.94 according to the service factor diagram.

At an ambient temperature of amb = 20C, the service factor diagram gives a service factor of fB3 = 1.0.

The service factor required is therefore

fBtot = 1.4 0.94 1.0 = 1.32

Fig. 2/3 Service factor "short-time duty"

Required torqueOnce the load situation (drive data) and the service fact have been clarified, then the required output torque can be deter-mined.

Input speedFor an identical power and output speed, in the selection tables 4-pole geared motors have priority over 6-pole motors.

As result of the very wide range of transmission ratios of SIMOGEAR gearboxes, it is hardly necessary to use motors with other pole numbers. In addition to the good availability world-wide, 4-pole motors generally offer the optimum solution regard-ing price, length, noise level and service life.

Further, from the modular system, motors with other pole num-bers can be mounted. As a consequence, the following special combinations can be implemented: Extremely high output speeds (2-pole motors) Extremely low output speeds (8-pole motors) Lower noise solutions (6-pole or 8-pole motors)

For inverter operation, the gearboxes are driven at variable speeds. When configuring the system, we recommend that the maximum input speed in continuous operation is maintained, wherever possible, at 1 500 rpm.

At higher motor speeds above 1 500 rpm you will generally ex-perience higher than average noise levels and a lower than av-erage bearing service life. This depends to a large extent on the transmission ratio and gearbox size in question. Furthermore, higher speeds additionally influence the thermal properties of the gearbox and service intervals.

Gearbox fasteningGearboxes and geared motors are normally secured by bolts of grade 8.8.

When the largest possible motor size is attached to the gearbox and with a higher load classification, elevated levels of vibration and/or smaller service factors, further measures need to be taken for flange-mounted designs of gearboxes and geared motors.

We recommend that you consider the following possibilities: Selection of a larger output flange Use of bolts of grade 10.9 Use of an anaerobic adhesive to improve the friction lock

between the gearbox and the mounting surface

Recommended bolt quality for DZ/ZZ and DF/ZF:

Helical gearboxes DZ/ZZ and DF/ZF with the smallest available output flanges must be bolted to the mounting surface with bolts of grade 10.9 (see table).

Recommended bolt quality for FF/FAF and KF/KAF:

Parallel shaft gearboxes FF/FAF and bevel gearboxes KF/KAF in combination with larger motors must be bolted to the mounting surface with bolts of grade 10.9 (see table).

Shaft load and bearing service lifeAvailable radial force

The radial forces either come from the driven machine (mixer, hoisting gear) or they are caused by the transmission elements.

The available radial force FRavail at the output shaft is obtained as follows: The required geared motor output torque T2 Average diameter of the mounted transmission element d0 Transmission element type, e.g. sprocket wheel

The transmission element type determines the additional factor C (see table).

Additional factor C for the transmission element type

Permissible radial force

The permissible radial force FR2 is determined by the required bearing service life, among other things. The nominal service life Lh10 is determined in accordance with ISO 281. Normally, calcu-lating the nominal bearing service life is completely adequate.

The bearing service life can be calculated for special operating conditions and in special cases on request, based on the modi-fied service life Lna.

The selection tables specify the permissible radial force FR2 for the output shafts of foot-mounted gearboxes with solid shaft. These table values refer to the force application point at the cen-ter of the shaft extension and are minimum values, which apply under the most unfavorable conditions (force application angle, mounting position, direction of rotation).

If the values in the table are not sufficient, or if other gearbox de-signs are being used, please contact Siemens.

Permissible axial force

If no radial force is present, then as permissible axial force Fax(tension or compression), max. 50 % of the permissible radial force can be applied.

Higher permissible radial and axial force

The permissible radial force load can be increased, taking the force application angle and the direction of rotation into account. Installing reinforced bearings also means that higher loads are permitted on the output shaft.

If higher radial or axial forces or combined loads comprising radial and axial forces occur, then please contact Siemens.

Note:

Bevel gearboxes B and K and helical worm gearboxes C in type of construction M1 with foot mounting on the face side:Maximum of 50 % of the radial force FR2 specified in the tables is permissible.

Helical geared motors ZB and DB in foot/flange-mounting designs:When transmitting torque through the flange surface, a maxi-mum of 50 % of the radial force FR2 specified in the tables is permissible.
